 Redis in the existing infrastructure (I believe you have already deployed Redis), it doesn’t need to bring extra to the
 operation and maintenance deployment. Cost and burden. With the high performance of Redis, *CoSky*
 provides ultra-high TPS&QPS (10W+/s [JMH Benchmark](#jmh-benchmark)). *CoSky* combines the process cache strategy + *

 借助于 Redis 的高性能， *CoSky* 提供了超高TPS&QPS (10W+/s [JMH 基准测试](#jmh-benchmark))。*CoSky* 结合本地进程缓存策略 + *Redis PubSub*
 ，实现实时进程缓存刷新，兼具无与伦比的QPS性能、进程缓存与 Redis 的实时一致性。
